Long ago I saw a book on the AMS (American Mathematical Society) or the MAA (Mathematical Association of America) bookstore website that would do geometry following the Erlangen program.
In the introduction, the authors indicated that a second book would be written about non-Euclidean geometry, and I then decided to wait until this second book was written.
Now I was thinking about buying the book but I cannot find it any more. I remember it was written by two authors -- one I think from the University of Texas and I think it was published in 2009.
Does anyone recognise this book?
Update 01/10/2017
I found the book I was looking for ( but I do think gave some wrong hints)
The book I was looking for was:
Continuous Symmetry, from Euclid to Klein
By Barker and Home, American Mathematical Society 2007, (mbk-47)
ISBN 987 0 8218 9300 3
(No part two yet , but hope it will come some time)
Thanks for all other suggestions and sorry for all wrong hints
You may be referring to Geometry by Ivan Izmestiev. I could not find any place to buy it, but perhaps you can request an inter-library loan at your local library. Although it is a fairly recent book, so "long ago", may not fit, although it is in the same spirit, and should be a valuable resource.
